Microwave imaging refers to the use of microwaves to capture images of real-world objects. While conventional optical imaging uses light waves to capture images, microwave imaging uses waves at microwave and millimeter-wave (mm-wave) frequencies. In this talk, we will be discussing how planar antenna arrays, operating in the 24GHz band, can be used to capture three-dimensional images of objects (especially people) in an indoor environment.

While microwave imaging is not a new technology, it has seen little commercial success due to the high cost of the large number of antennas and radio transceivers required to build such a system. This talk will therefore also investigate how these systems can be made commercially viable, such as (a) using low-cost, noisy RF components, or (b) removing most of the antennas from the array and using compressive sensing techniques to generate high-quality images from the resulting sparse antenna array.
